The Impact

In this research, the design of the force measuring system on main landing gear weight drop test for the LSU series that developed by LAPAN was carried out. The principle of this machine is to apply the load according to the weight of the aircraft on the main landing gear and drop it at a certain height assisted by the guiding rail. At the bottom of this machine there is a impact platform where each angle is mounted with a load cell that functions to measure the reaction force due to the impact of the main landing gear. In addition, there is a data acquisition system whose function is to process the output signal from load cell and display measurement data. The data acquisition system used consists of DAQ measurement hardware made by national instruments and LabVIEW software installed on a PC. The design of this testing tools aims to carry out a dynamic impact test on the main landing gear structure of the UAV. In this study, static calibration has also been successfully performed on the impact platform and shows consistent results for various test masses.

Graphical Presentation

This document guides to an efficient use of FDVCAS system. FDVCAS is a reconstruction, playback, interactive visualization tool, which collects, stores, processes, analyses and present the flight data in high fidelity graphical presentation in 2D and 3D format. It synchronizes and presents in both graphical and synthetic visual form to the extends of analysing the impact of the data on the system in 3D graphic animation. The existing process involves in capturing the data from different input sources and formats, analysing the features of the data monitoring is done manually in offline in a unsynchronized fashion, This is difficult, time consuming and requires highly skilled technical expertise as it is visualized in plain data form. The above standard procedures followed shall be integrated and automated with minimum intelligence to be built, in with the system. In order to analyse the flight data in a coherent way it is required to integrate both 2D and 3D form The proposed concept is the Development of a system with a single solution by providing data display, graphical charts and replay features with a sophisticated graphical user interface, which is super imposed on the outside window imagery. FDVCAS consists of Bypass data acquisition system, Outside Window Imagery (OWI) system with graphical analyser. Bypass data acquisition system receives data from aircraft recorder and transmits the data in engineering format to FDVCAS system. The OWI system has three main modules namely, 3D Visual module, GUI based Graphical analyser and Warning display module. The warnings and the graphical plots are super imposed on the 3D Visual.

The paper introduces the status of rolling bearing life testing machine in China first. Then, the paper mainly focuses on the design of vibration signal data acquisition system for rolling bearing life testing machine. The system is developed for a rolling bearing manufacturer based on Labview with perfect functions according to the requirement of the customer. The rolling bearing manufacturer can set up different measurement time and time interval for data record to carry out test according to the requirement of its customers. The developed vibration signal acquisition system is not subject to testing machine, which can run only that the sensors are installed on the measurement locations of testing machine. The developed system can be used for different rolling bearing life testing machine, so it has good application perspective in future.

Demand Information

Friction wear testing machine is generally used in researches of various friction wear mechanisms, explorations of influences factors, and property evaluations of friction pair materials. Measurement accuracy and automation level of the friction wear testing machine directly influence the precision of data acquisition and analysis processing, as well as the intuition of data displaying. Based on virtual instrument LabVIEW, a data acquisition system of friction wear testing machine was developed. Hardware of this data acquisition system mainly consists of sensors utilized as acquiring information on rotate speed, normal pressure, friction force and temperature, as well as signal conditioning module and data acquisition card. Utilizing the LabVIEW, data processing and interface displaying software was programmed. Debugging results confirmed that the developed system can accurately acquire the demand information when operating the friction wear testing machine, also intuitively display these obtained information in real-time. Therefore, the developed data acquisition system satisfies the demand of precisely acquiring information related to friction wear testing of experimental materials.
